Anxiety & Your Gut Health: The Gut Brain Connection


Have you ever noticed that your appetite changes depending on your mood or stress levels? Have you ever had an upset stomach during moments of anxiety, or instantly felt hungry when seeing your favourite food? These are just some examples of the intricate ties between our mind and our digestive system. This mysterious link is often referred to as the gut-brain connection. In this article, we'll explore this connection and delve into ways to enhance both gut health and mental well-being.


Understanding the Gut-Brain Connection

The gut-brain connection is not merely a coincidence; it's a complex relationship deeply rooted within our body's systems. It represents a dynamic two-way communication pathway between the central nervous system and the enteric nervous system, which encompasses the organs and microbiome found in the digestive tract.


Your gut is home to trillions of microorganisms, collectively referred to as the gut microbiome. Among these microbes are both good and bad bacteria, which play a vital role in your overall health. An imbalanced microbiome, with an overgrowth of harmful bacteria, has been linked to various health issues, including conditions like irritable bowel syndrome (IBS) and anxiety.


Additionally, the gastrointestinal (GI) tract produces neurotransmitters and hormones, like serotonin and dopamine, that impact brain function and mood. When your gut microbes are unbalanced, it can lead to reduced production of these "happy hormones", which can result in stress, anxiety, and depressive symptoms.


Anxiety & Gut Health

It’s a little too easy to get stuck in a cycle where gut issues cause spiraling anxiety, which worsens the gut issues, which then causes more anxiety. Let's take a look at why.


When you're anxious or stressed, your body enters "fight or flight" mode, redirecting blood flow away from the digestive system. This can lead to digestive issues like stomachaches, cramps, discomfort, constipation or diarrhea, bloating, and gas, which can in turn lead to social discomfort and anxiety. Additionally, chronic anxiety can disrupt the balance of bacteria in your gut, potentially exacerbating gut-related issues. This information tells us that while the health of your gut can influence your anxiety levels, your anxiety can also have a direct impact on your gut.


Let’s take a look at what anxiety might feel like:

  • Frequently feeling worried, nervous, tense, or restless

  • Feeling an impending danger or doom

  • Increased heart rate

  • Increased breathing (hyperventilating)

  • Sweating

  • Shaking or trembling

  • Feeling weak or tired

  • Brain fog or difficulty concentrating

  • Insomnia and sleep troubles

  • Fatigue

While occasional, mild feelings of anxiety are a common human experience and not typically cause for concern, if anxiety begins to disrupt your daily life and result in physical symptoms or gut issues, it's important to address and manage it effectively.


Here are some techniques that are proven to manage anxiety:

  1. Stress Reducing Activities: Stress-reduction techniques, such as meditation, mindfulness, and movement, can reduce feelings of anxiety and positively impact your well-being.

  2. Avoid Excessive Alcohol and Drug Use: Excessive use of alcohol and other substances can worsen your anxiety and lead to other health issues. Where possible and safe to do so, try to limit or avoid the use of alcohol and recreational drugs.

  3. Exercise: Engaging in regular exercise can help to relieve anxiety by reducing stress. Exercise does not have to be intense or fast-paced to be beneficial. If you prefer walking, stretching, yoga, Pilates, or dance, try these instead. Moving your body in a way that feels good to you will help you to be consistent in your routine.

  4. Professional Support: Speaking with a counsellor, psychologist, or other mental health professional can help you to better understand and manage your anxiety. A trained professional can provide you with tools and strategies to change negative behaviours and thought patters, regulate emotions, improve self-confidence, and enhance problem-solving and stress management skills.

Here are some steps you can take to enhance your gut health:

  1. Limit Processed or Sugary Foods: Heavily processed or sugary foods can disrupt the growth of good bacteria. Avoiding excessive sugar consumption can help to restore gut health.

  2. Dietary Changes: Incorporate more fruits, vegetables, and whole grains into your diet. Consider probiotic-rich foods, and a balanced diet containing fiber, vitamin D, vitamin C, zinc, and magnesium. This can help to support a balanced gut microbiome and improve digestive function.

  3. Avoid Excessive Alcohol and Drug Use: Excessive alcohol or drug use can halt the growth of good bacteria, leaving room for the bad bacteria to take over and creating a gut microbiome imbalance.

  4. Professional Support: If your gut issues are persistent or severe to the point they are impacting your daily life, you should speak to a professional. A dietician, naturopath, or doctor that specialises in gut health can help you to identify the cause and provide treatment options.

It's clear that anxiety and the gut are deeply connected, to the point where the health of one can powerfully impact the other. It’s amazing how intertwined our body systems are! The research into the gut brain connection opens up new avenues for managing anxiety and boosting the health of both your body and mind. The body all works together and a multifaceted approach that includes some gut-healing, as well as some anxiety reduction, can be a great start to solving your gut-brain puzzle.
